Ok I have my new ep45t-usb3p o/ced to 4.0 and pretty well useing the same voltages etc. from old ep45t-ud3lr board, I will have to see if i can crank down some of the voltages to get them lower that what i needed before, only thing in bios there is some new things i duidnt have on old board like channel A and B dat vref and channel A+B address vref, the bios setting is .75 on all and i have them all set to normal, is the correct or should i set them to .75 or some other number, overall impression of the board is I realy like it, My system is running abit cooler as well, maybe cause of the better heatsinks?
